No. DisplayLink is video out over a regular USB protocol/connection, not “alt mode”. It’s for when you don’t have true video out. It’s compressed to hell and stupid.

Video out is frustratingly uncommon. Samsung, some Sony’s, and only very recently Pixels. Google was vocally against video out for a long time. And SD cards (gotta pay for drive). You were expected to roll the dice with whether Chromecast works with a random TV and wifi combination.

Pixels were popular for two reasons: the camera and “basic black rectangle” device (RIP Nexus).
